Hi Vijay,
Thanks....is "replace-brick commit force" also can possible through Ovirt Admin Portal or do i need to use the command line to run this command ??
Also i am looking for HA for glusterfs...let me explain my architecture more :-
1. I have 4 node glusterfs cluster....and same 4 nodes i am using as Ovirt HV nodes (storage + compute).
2. Now if i mount it in Ovirt...it will mount on one node ip address....and if this node goes down...all my VM will pause...
3. I want to use HA or LB through CTDB or HA proxy...so even any node goes down the VM will not affect...
4. I am ready to put two additional node for HA/LB purpose.....
Please suggest me good way to achieve this....

Hi,
I have one question regarding the gluster failover...let me
explain my current architecture,i am using Ovirt with gluster...
1. One Ovirt Engine (Ovirt 3.4)
2. 4 * Ovirt Node as well as Gluster storage node...with 12
brick in one node...(Gluster Version 3.5)
3. All 4 node in distributed replicated structure with replica
level =2...
4. I have one spare node with 12 brick for Failover purpose..
Now there is two questions :-
1. If any of brick failed...how i can failover this brick...how
to remove the failed brick and replace with another brick....??
Do i need to replace the whole node or i can replace the single
brick ??
Failure of a single brick can be addressed by performing "replace-brick commit force" to replace the failed brick with a new brick and then trigger self-heal to rebuild data on the replace brick.
2. If one of the whole node with 12 brick down and can not come
up...how i can replace it with the new one....do i need to add
two node to main the replication level... ??
You can add a replacement node to the cluster and use "replace-brick commit force" to adjust the volume topology. Self-healing will rebuild data on the new node. You might want to replace one/few bricks at a time to ensure that your servers do not get bogged down by self-healing.
